IMPROVEMENT IN HORSE HAY-PORKS.

The Schedule referred to in. these Letters Patent and making part of the same.

T0 all whom muy concern:

Be it known that I J OHN J. DE GRUMMOND, of Knoxville, in the connty of Knox, and State of Illinois, hzwe invented n new and vztlnnble Improvement in Hey-Forks; mid I (lo hereby declare that the following is t full, clear, and exact description of the con strnotion md operation of the seme, reference being hm.l to the nnnexed clrnwings, nmk'ingpart of this spe- A ready and eiiicient mzrnner.

The letters A, of the drmvings, represent two heavy forks, of the form shown, nnd pivoted together at the p'oint a.

The letters B represent two n'rms or levers, pivoted together at the point c, and nlso pivoted to the forks A att the points 71..

The letter n represents n block, pivoted by the saune bolt that unites the levers B, and holding npullev, s, ns shown. I nlso make El; small opening in the tlnngo of said block, nt the point 'n, for fitstening the.ropeb y which the forks tre nctnzrted.

' The letter 1: represents {L block, pivoted to the forl;s

by the seme bolt that unites them, and which is {u A rnnged for holding the pnlley' y.

The rope for aotuating the t'ork is t'astened to the opening in the tlnnge of block n, und is passed around the pnlleys s and y.

The above-mentioned devices, when nrrnnged as shown, serve 'as eflicient means for raising large bodics ot hay and other con1rn0dities of a like character. They are cheap of construction, end simple in opera-- tion.

\Vhttt I claim ns my invention, and desire to seure by Letters Patept, is

A,hny-fork, having forks A,levers B, blocks n and r, end pulleys s and y, constrncted and n-rrnnged substantially ns specified.

In testimony that I elni11 the above, 1 hit-V6 hereunto snbseribed my name, in the presence of two wit nesses.
